RT 4.0.0rc7 Released

This release contains several weeks of bug fixing and more than 100 commits in the push for 4.0.0. It contains many bugfixes and a reorganization and general cleanup of the core documentation. Barring regressions, this should be the last non-documentation update before 4.0.0.

DOCS * Massive reorganization of docs/, README and the upgrading docs by alexmv * Document how to deploy RT under the root using a sublocation * Add more web deployment examples for non-apache webservers * Update all of the documentation in RT_Config.pm * Remove all references to 'true' or 'false' in the config, replacing them with valid examples instead
